However, the bird was re-found at the weekend and with space available on a flight I found myself picking up Al early morning and setting off for the airfield. Luckily we received news the bird was still present from the ranger on the island so we were pretty confident! At the very least Papa was a new island for me.
Jonathan (the ranger) met us of our flight and led us to where the bird was feeding unconcernedly in long vegetation. For the next couple of hours it played hide and seek occasionally showing but only partially whilst feeding voraciously.
Our patience was rewarded though when it flew onto an adjacent dry stone wall.
A great trip and a fantastic island. Although we didn't see many other birds I did pick up a flyover Lapland Bunting and a small flock of barnacle Geese. With a relatively uneventful flight home (apart from the plane not starting and having to be jump started with the airfield fire engine!) it was a long but satisfying day.
Hopefully this will be the 1st Chestnut Bunting on the British list! The close views gave us opportunity to check for any signs of captivity such as abnormal feather wear and broken / damaged claws.
